ASSEMBLING AND nrsAssEMBLr is nnvrcn.

Application filed April 24, 1925, Serial No, 25,674.

This invention relates to assembling and disassembling devices for use in connection with the transmission mechanism and mag neto of Ford automobiles, the device being of the character disclosed in my co-pending application, Serial No. 7 53,259, filed Decemher 1, 1924.

An object of the present invention is to provide a form of magnet engaging disk which, while used substantially in the manner illustrated and described in the above mentioned application provides a different -form of engagement with some of the elements of the magneto and transmission mechanism.

VJith the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illus trated in the accompanying drawings and pointed out in the appended claims.

In the drawings -Figure 1 is a top plan View showing the base of the assembling and disassembling device as mounted upon a bench or support, the remainder of the device being omitted.

Figure 2 is a sectional view taken substantially on the line 2-2 of Figure 1 showing the device engaged by the transmission brake drum.

Figure. 8 is an edge View oi the disln l igure 9 is an edge view oi the magnet engaging disk.

Figure 10 is a fragmentary sectional view taken substantially on therline 10-10 of Figure (3.

Referring to the drawings in detail wherein like characters of reference denote corresponding parts, there is illustrated a 50 base which may he of the character shown and described in my before mentioned application and which is mounted upon a suitable support such as a work bench or table 21. This base is provided with an annular boss 22 and a central opening 23, the wall of this opening being pro- Renewed October 11, 1926.

vided with an annular shoulder 24 from which extends a pin 25. Thepurpose of this pin will be later apparent.

The well known form ofm-echanism with which the invention is adapted for use includes a fly wheel and a magnet-o designed as a unitary structure and a transmission mechanism. This transmission mechanism includes'a brake drum 26, a slow speed drum and a reverse drum, the two latter drums not being illustrated. The transmission shaft is indicated at 29 while the flange or disk at one end of the shaft is shown at 30. The transmission mechanism further cludes a plurality of triple gears, the pins of which are indicated at 48.

The fly wheel is indicated at 33, the ring I gear at and the magnets at 35, the latter being secured to the fly wheel by bolts 36. 5 As previously stated this structure provides a unit which comprises a portion of the mechanism of a Ford automobile and as this mechanism is well known its operation and structure will not be specifically described.

The invention provides means for conveniently supporting the unit so that access may be had to its various parts for the purpose, of removing and installing them and to do this, the invention includes the base plate 20 previously mentioned. The boss 22 of this'base plate is of a size to it within the recessed face of'the fly wheel 33 as shown and described in the application previously mentioned, so thatthe face of the wheel may rest upon this boss with the transmission drums extending downward through the opening 23 of the plate and through an opening '3'? provided in the table W or bench 21. This arrangement is illustrated and described in my co-pending ap plication. The entire unit may thus be supported upon the base plate in a manner to permit of the said unit being revolved so as to conveniently reach the bolts 36 and permitof the magnets and ring gear being conveniently removed from the'fiy wheel. 1

The present invention has particularly to do with means for supporting the mechanism in position for the removal of the transmission drums "from the fly wheel and for separately holding these drums. For this purpose there is provided a disk l1 which is illustrated in detail in Figures 6 and 9 of the drawings. This disk is of a diameter to it within the opening 23 of the base 20 and notches 47.

to rest upon the annular shoulder 24 as shown in Figures 2 and 5 of the drawings and when in this position to receive the pin 25 within an opening 42 provided inthe disk so as to hold the latter against rotation. Upon one face, the disk 41 is provided with an annular groove 43 which is arrange concentrically around a central opening 44 provided in the disk, the cross sectional area of the groove being of a size to receive the heads of the bolts 36. Extending transversely across the groove is one or more diametri Cally disposed ribs 44 which are adapted to be engaged by the heads of the bolts 36 so that the fly wheel and the mechanism carried thereby will be held against rotation. The mechanism may thus be conveniently removed or replaced.

Upon its opposite face, the disk 41 is provided with a hub 45, while surrounding this hub is an enlarged portion or boss 46, the latter being provided with spaced grooves or The hub 45 is adapted to fit within the brake drum as illustrated in Figure 2 of the drawings, while the grooves or notches 47 receive lugs 47 which extend inwardly from the brake drum so that the latter will be held against rotation.

The disk 41 is provided with an annular shoulder 48 which extends around the wall of the opening 44 and this shoulder is adapted to supporta disk 49 upon which the flange 30 of the transmission shaft 29 is adapted to rest, or the hub or shaft of the trans mission brake drum 26 may be supported as shown in Figure 2. The disk 41 is further provided with spaced openings 50 which receive the pins 48 of the fly wheel which carry the triple gears, so that the fly wheel may be supported upon the disk 41 and held against rotation for the removal of the magnets 45.

The invention is susceptible of various changes in its form, proportions and miner details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claims.

Having described the invention what is claimed is 1. An assembling andv disassembling device for automobile transmission mechanisms and magnetos comprising a base plate having an opening therein, a disk removably supported within the opening, said disk having an opening therein, means included in the disk and surrounding the opening to engage the magneto to support the latter against rotation and interlocking means between the disk and base plate.

An assembling and disassembling de vice for automobile transmission mechanisms and magnetos comprising a base plate having an opening therein, a disk removably supported within the opening, said disk having an opening therein, interlocking means between the disk and transmission mechanism to hold the latter against rotation and interlocking means between the disk and base plate.

in assembling ant d sassembling device for automobile transmission mec ianisms and magnetos comprising a base plate having an opening therein, a reversible disk removably supported within the opening, means upon one face of the disk for interlocking engagement with the magnetov means upon the opposite face of said disk for interlocking engagement with tie transmission mechanism and means to hold the disk against rotation.

4. ran assembling and disassembling device for automobile transmission mechanisms and magnetos comprising a base plate having an opening therein, a reversible disk removably supported within the opening, said disk having an opening therein and i annular groove surrounding the opening to receive the heads of the magnet attaching bolts of the magneto, means within the groove to engage the bolts and hold the magneto against rotation, means upon the opposite side of the disk for interlocking engagement with the transmission mechanism and means to hold the disk against rotation.

5. An assembling and disassembling de vice for automobile transmission mechanis and magnetos con'iprising a base plate having an opening therein, a reversible disk removably supported within the opening, said disk having an opening therein, a hub surrounding the opening upon one face of t a disk, said hub being adapted to fit within the transmission drums and having spaced notches around its outer periphery to re ceive lugs upon the inner periphery f the drums and means to hold'the disk against rotation.

In testimon whereof I a fix 1v signature.
